Can i use the real hair to do the knotting as cyber hair? Is there a safe hair extension method in the market?
I am not an expert in hair extensions, so I cannot comment if one is safer or better than the other. In general, if there is a constant pulling on your native hair (which you will feel), it may cause traction alopecia over a period of time. The extensions that are fixed in place have more traction alopecia than those that you place and move around by yourself.
